“…The rising prevalence of underweight among females may be explained, at least in part, by recently highlighted body image issues resulting in a tendency toward the “ideal image” of the thinner female, 62–64 coupled with a possible increase in dieting behavior and eating disorders, as implied here (Table 3, see mental disorders) and by others. 65 Preliminary analysis of the prevalence of eating disorders among females in our study population demonstrated a clear upward trend (from 0.00% to 0.10%, 0.23%, and 0.21% among females who were born before 1981, during 1981–1985, 1986–1990, and 1991 and later, respectively).…”

The increasing prevalence of abnormal body mass index (BMI), mainly obesity, is becoming a significant public health problem. This cross-sectional study aimed to provide a comprehensive view of secular trends of BMI, and the associated socio-demographic variables and comorbidities among adolescents with abnormal BMI. Individuals of the study population were born mainly between 1970 and 1993, and were examined at 16 to 19 years of age during the years 1987 to 2010, at 1 conscription center in the northern district of Israel.The study population included 113,694 adolescents. Univariate and multivariable logistic regression models were used to investigate the associations between BMI categories, socio-demographic variables, and medical conditions.A downward trend in the prevalence of normal BMI among both male and female adolescents was obtained, while trends of overweight and obesity (in both genders) and underweight (only among females) rose. Socio-demographic variables such as religion, education, family-related parameters, residential environment, country of birth, and origin were all associated with different risks for abnormal BMI. Obesity was associated with higher risk for hyperlipidemia, endocrine disorders (only in males), knee disorders, and hypertension type I + II (in both genders). Overweight was associated with knee disorders (only in females). Underweight, exclusively in males, was associated with increased risk for endocrine disorders, proteinuria, and cardiac disorders. Hierarchical clustering analysis revealed the intricate relations between gender, BMI, and medical signatures. It brought to light novel clusters of diseases that were abundant among populations having above-normal BMI or underweight males. Furthermore, above-normal BMI was associated with a lower rate of cardiac anomalies and scoliosis/kyphosis, whereas being underweight was associated with a lower risk for hypertension and flat foot.This study provides a reliable and in-depth view of secular trends in height, weight, and BMI of male and female adolescents. It supports previous associations between abnormal BMI and demographic variables and comorbidities, while uncovering novel associations, mainly regarding medical signatures of each gender–BMI group. This might lead to better monitoring, early detection, prevention, and treatment of various conditions associated to abnormal BMI categories and gender groups.

“…In contrast to previous cross-sectional research (e.g., Tylka [13]) or research which explored direct associations between variables presented in our study (e.g., Mendonça et al [23]), this research permitted a more thorough testing of associations between body satisfaction, healthy and unhealthy eating, restrictive dieting and BMI in the non-clinical group of under-and healthy-weight adolescents. Thus, our research expands on previous research conducted in general population of adolescents [26] or only in groups of overweight and obese adolescents [27,28], and shows that these associations are true also across under-and healthy-weight adolescents and in a large sample of both male and female participants.…”

Body satisfaction and body weight in under- and healthy-weight adolescents: mediating effects of restrictive dieting, healthy and unhealthy food intake

et al. 2018

Purpose Theoretical models, such as the transdiagnostic model of eating disorders highlight the role of cognitive factors (e.g., the way people perceive their bodies) and their associations with maladaptive weight management behaviors resulting in underweight. This paper aims at testing the indirect association of adolescent's body satisfaction and body mass index (BMI) through restrictive dieting, healthy eating or unhealthy eating as well as moderating role of adolescent's weight status. Methods The study was conducted in 16 public middle and high schools in Central and Eastern Poland. A sample of 1042 under-and healthy-weight white adolescents aged 13-20 (BMI: 12.63-24.89) completed two self-reported questionnaires (fruit, vegetable, and energy-dense food intake) with a 11-month interval. Weight and height were measured objectively. Multiple mediation analysis and moderated multiple mediation analysis were conducted to test the study hypotheses. Results Adolescents less satisfied with their bodies were more likely to diet restrictively and at the same time ate more unhealthy energy-dense food rather than healthy food, which in turn predicted lower BMI. No moderating effects of weight status were found. Conclusions Low body satisfaction is a risk for restrictive diet and unhealthy food intake. Prevention programs may target under-and healthy-weight adolescents who are highly dissatisfied with their bodies, have a high intake of energy-dense food and apply a restrictive diet at the same time. Level of evidence Level III: longitudinal cohort study.

“…16 A study of Brazilian adolescents reported body image distortion in all BMI percentile classes; 35% of underweight adolescents did not regard themselves as thin, and 39.1% of overweight adolescents and 62.1% of obese adolescents did not correctly categorize their weight. 17 Body weight misperceptions have been consistently demonstrated in adults as well as in adolescents. In a nationally representative sample of Australian adults, males significantly underestimated their weight status compared with females, whereas females significantly overestimated their weight status compared with males.…”

ObjectivesThis study aimed to examine the prevalence of weight misperception and to explore the association of weight perception with physical activity and dietary intake.MethodsA population-based, nationally representative cross-sectional survey was conducted of 920 Thai adolescents aged 13 to 24 years. Respondents were selected using stratified multistage sampling. Respondents who agreed to participate were asked to complete the Youth Risk Behavior Questionnaire.ResultsFemales were more likely than males to misperceive themselves as overweight (21.8% vs. 11.7%), whereas males were more likely than females to misperceive themselves as underweight (12.3% vs. 3.4%). Males were more likely than females to report a high intake of vegetables (45.7% vs. 38.0%), milk (39.1% vs. 38.0%), 100% fruit juice (20.9% vs. 17.7%) and soda or pop (38.5% vs. 20.6%). Males were also more likely than females to report vigorous physical activity of more than 60 minutes per day (38.1% vs. 21.3%) and vigorous exercise to strengthen or tone muscles (37.3% vs. 13.2%).ConclusionsGender differences in dietary intake and physical activity were identified. However, there were no significant differences in dietary intake and physical activity between adolescents who correctly perceived themselves as overweight and those who misperceived themselves as overweight.
